Hi, I have a setup that just does admin logins for NAS equipment, some of it presents via PAP and some of it peap/mschapv2. When the user is rejected I do a linelog or sql insert, capturing a failure reason from each module. Basically an EAP reject of a user creates two entries to the logging. I do failure logging within the inner-tunnel VS as well as the default because I wanted it to capture a failure reason to the line log based on the module-failure-reason string, which is lost after the eap session rejects and can't be seen in the default. As you commented in an email from last week, updating the outer.control variable to try and pass module-failure-reason doesn't work due to the access-challenge presenting a new session. I'm also doing some stuff in the authorization section which can reject a user based on some ldap information. I thought I could perhaps just update the default tunnel post-auth reject section to not do a linelog if auth-type has been set to EAP but it doesn't work when clients are rejected in this ldap section; the EAP auth-type is set but it never authenticates as the reject is triggered first, and so a linelog would never be recorded in the inner tunnel post auth reject section. I hope that's not too confusing, it's hard to explain.

Hi,

Just wondered if someone could explain the reason why, on rejection

of EAP authentication, an access challenge request is sent out to the NAS, and whether it's something we can control or not?

I assume you're referring to the fact that the inner tunnel reject is sent as an outer access-challenge? The packet flow is this: C: Access-Request EAP / TLS-setup S: Access-Challenge EAP / TLS-setup ... C: Access-Request EAP / TLS / inner access-request S: Access-Challenge EAP / TLS / inner access-reject C: Access-Request EAP / TLS [ack] S: Access-Reject EAP / reject Basically, the protocols send the inner reject as a TLS frame, so that the client can't be tricked by a fake reject. The client then ACKs it, and the server then sends the RADIUS-level reject. So no, you can't turn it off - it's part of the protocol specifications.
